Using the retina display on a macbook pro

Hi,

When I run a (GLUT based) OpenGL program on my retina MacBook Pro I get a window size relative to the 1440x900 resolution that is "simulated" on the retina display. That would be fine by me except that zooming in makes it clear that each pixel is actual four retina pixels, so OpenGL does not render at the true resolution.

Am I overlooking something simple?

Otherwise, I would be very interested in knowing if anyone has managed to get "retina OpenGL contexts" associated with windows and, in particular, if it is possible from GLUT (as I expect it isn't ... but who knows?). I expect I need to go with glKit?
